coil-Loading Small-Arms, of which the following is a full, clear, and exact description.

In hitherto known automatic loading weapons with changeable magazines the .1'- rangement is such that, after the last cartridge in the magazine has been fired off, the

rearwardly moved breech bolt is retained in its rearward position by the cartridge feed plate or by a special arresting member,

thereby indicating to the marksman that the magazine in the weapon is empty and must be replaced by a full one. This exchange of the empty magazine for a full one 1s, as

is well known, easy and rapidpin order,

however, to prepare the weapon again for firing, it is necessary with the devices hitherto known to partly or completely pull back the breech bolt and allow it again to advance in order to push a cartridge into the barrel. This movement takes moretime than the simple exchange of a magazine, as the Weapon has to be turned round or to be put from one hand into the other and then back again; this has been found 'to be a draw back, the removal of which is the object of the present invention.

Every self loading weapon after having fired the last cartridge, must be ready for "'gloading and, after the fitting thereto of a inew magazine, must be again immediately ready for firing; the manner in Wl'llCll this requirement is complied with isshown in the accompanying drawings as applied, for. example, to a self loading pistol, Mausers system.

Figure 1. shows the right hand side of the pistol, partly in section to show the novel parts, the last cartridge out of the magazine and in the barrel ready for firing. Fig. 2 shows the breech bolt held back in-the usual way by the cartridge feed plate, after the last cartridge in the magazine has been fired off, the empty magazine being still in the weapon. Fig. 3 shows the breech bolt held back by the cartridge ejector after the removal of the empty magazine from the weapon. Fig. 4 is a section on line I.l of Fig. 1, looking in the direction of the arrow. Fig. 5 is a section on line II-1I of Fig. 3

looking in the directionof the arrow. Figs. 6 to 9 show details.

By referring to Figs. 1 to 5 it will be seen that the spring ejector a, a detent b, and

the magazine holder (L-are mounted at the 'side of or 'behind each ,other in the stock A (that is, that part on which the barrel B with the breech casing C is slidably mounted and 'guided) immediately at the rear limit of the magazineaperture. The detent b is influenced by the spring f and forms in its;

co-action with the spring ejector'a on the one hand and the changeable magazine Don the other hand, the .main feature ofthis, in vention.

Supposing the various parts of the weapon to be in the position shown in Fig. I, all the partsfwill have assumed the position shownin. Fig. 2 after the last cartridge has been delivered from the magazine, that is to 'say, the cartridge feed plate p of the magazine D, by the action of the feed springZ thereon,

passes in front of the 'rearwardlyprojected breech bolt E and prevents, as is well known, this latter from advancing to its locked posi tion. If the empty magazine is now removed from the weapon to be replaced by a full one, thebreech bolt would, in the usual way,,be released from the feed plate, and consequently resume its closed position.

This isthe known operation as described at the beginning of this specification and which is disadvantageous because the weaponis not ready for firing afterthe full mega zine has been introduced, for the reason.

first of all, that the breech bolt has to be pulled back by 'hand'until it is able to engage the uppermost cartridge and push it ,into the barrel- Attempts have already been made, by introducing special arresting members; to meet this drawback, but they.

have only succeeded. so far that the breech bolt has not had to be pulled back the whple distance of its working movement but only a short distance in order to be released from the member holding it and to be able to push a cartridge from the new full magazine into thebarrel. The saving of time by this means is, however, so slight that ,it is .not worth the arrangement provided, as a special handle is necessary for drawing back the breech bolt whether for a greater or smaller distance.

Accordingto the present inention the arrangement is such that after the last cartridge has been. delivered by the magazine,

the breech bolt is held back by the feed plate of the magazine in the same manner as heretofore, (Fig. .1) the breech bolt, however does not immediately advance to its closed position after the removal of the empty magazine but is held fast by the spring ejector a, as shown in Fig. 3, until it is released from the latter by the fitting of a new full or empty magazine, when, in advancing to its closed position, it simultaneously pushes a fresh cartridge out of the magazine into the barrel This is eliected by the movability of the spring ejector (which does not hinder the freedom of movement of the breech bolt when shooting and when a magezine is in .the weapon) being interrupted when the magazine is removed by means of a detent 12 until a new magazine is introduced. When this has been done the ejector again obtains its spring movement and is then able to eject the empty cartridges.

The details necessary for the above described operation are shown in Figs. 6 to 9.

Fig. 6 shows'the ejector a, which, contrary to the form hitherto adopted, has only one laterall projecting nose a under which the detent (Fig. 7 passes when the free'move ment ofthe ejector is to be temporarily interrupted. The magazine holder (1 (Fig. 8

which holds the magazine in the weapon'm known manner, and the detent b are both infiuenced by a duplex spring 7 (Fig. 9.). The

. arrangement of these parts in the wea on is able to pass into a notch or recess pr0-- and their action will be understood by re erring to the drawing.

he ejector is -constantly pressed upwards by its 5 'ring atif isinot, as shown in Fig. 1, held down by the breechbolt while the latter is in its closed position; if, however, the breech bolt is-in its open position, the ejector vided for. this-purposein the underside oi the fore part of the breech bolt Fig. 2) and is again pressed down by the fol owing closing movement ofthe breechbolt if not mea n-( while held by the intervention of a special detent b and thereby prevented from any downward movement. This latter takes place when the empty magazine is taken out spring of the weapon in order to bereplaced by a thereby prevented 'frorn moving downwards and consequently holds the breech bolt in its rear ward (open) position, (instead of'it be-- ing held by the feed plate which was removed with the magazine) until the projection 0 of a newly'introduced filled magazine again presses back the detent I), whereupon the ejector is relased by the latter and the'breech bolt is capable of advancing without hindrance to its closed position during which it simultaneously pushes the uppermost cartridge out of the magazine into the barrel; The weapon is now in the condition shown in Fig. 1, ready for firing again.

What I claim as my invention, and desire to secure by Letters Patent is:

1. In a self-loading small arm having a detachable magazine, a device for automatically putting the weapon in readiness for fir ing when changing magazines, comprising a spring ejector for holding the" breech bolt back when the magazine is removed, a detent for engaging said ejector, said detent being adapted to be disengaged from said ejector by a fresh magazine whereby the breech bolt can resume its closed position and thereby I ush a cartridge from the magazine into the arrel.

2. lnxself-loading small arms, the combination with the breech bolt of an ejector havinga'projectingnosaa notch or recess in the underside of'the nose'of the breech bolt into which the ejector can pass, a spring-pressed detent, and a projection on the magazine which holds the detent against the action of its spring, which detent, when the magazine is removed, is pressed forward so as to come under the nose of the-ejector when the latter has risen into] the notch or recess in the breech bolt and the latter is in the fully open position. j T

3. In a fire-arm having a breech bolt, a detachable magazine, means operated by the magazine for holding back said breech bolt when the magazine is empty, means for holding back said breech bolt when the magazine is removed, and means for releasing said last named means when a fresh magazine is introduced. I v 4;. In a fire arm having a breech bolt, a detachable magazine having means for holding back said breech bolt when the magazine is empty, and acatch mechanism adapted to be interposed in the path of said breech bolt when the magazine is removed, so as to hold said breech bolt in its open position, and means connected with the magazine for releasing said catch mechanism when a fresh magazine is introduced.

In witness whereof, I have hereunto si wltnesses.
